Description
Lost in HCM lists the Snap-on TEC12LA Torqometer under the plain code “U.S./ Metric Light Signal – TEC12LA”. It is a 3/8 inch drive dial wrench with a signal lamp and two scales. Its twin, the TEC12LAC with Chart, adds a document to the same tool. So pick that one if your file needs paper on day one.
Why kg·cm matters for the Snap-on TEC12LA Torqometer
Air conditioner, compressor and home appliance plants in Vietnam often build to Japanese drawings. Those drawings tend to give small fastener values in kgf·cm. The TEC12LA reads kg·cm on its metric scale, so an operator takes the value straight from the drawing. On the other side, the in-lb scale serves U.S. customer specs. As a result, one tool covers both document sets on a line.
Plain code or chart twin?
Snap-on’s CAT1500i U.S./Metric table says its listed wrenches come without a certificate of calibration. A certificate version is available, and Lost in HCM describes that twin as with Chart. It does not state what the chart contains, so ask before you order the C code.
The plain TEC12LA fits when:
- your metrology room checks each new wrench before release;
- several stations need the same tool, and the budget must stretch;
- a spare wrench only needs a cross-check against a checked master.
On the other hand, choose the chart twin for a customer audit or a receiving rule that wants a document first.
Catalog figures behind the TEC12LA dial
- Square drive of 3/8 inch on the head
- Kilogram-force centimeter side to 175, marked every 5 kg·cm
- Inch-pound side to 150, marked every 5 in-lb
- Length 9-29/32 in and width 2-11/16 in, per the catalog
- Head depth 1-1/4 in, with the square drive left out of the figure
- PB9 storage case and a Light Signal dial
Snap-on files the TEC12LA under Standard 2% Accuracy. Snap-on’s UK brochure gives that grade a ±2% window from one fifth of full scale to the top. So keep targets above 35 kg·cm, or 30 in-lb.
The lamp at an audit station
Per Snap-on, a Signal model has a built-in lamp that flashes once the set torque arrives. So an auditor can watch the part, then glance at the dial when the lamp shows. That helps on long shifts with many small joints. However, the lamp only marks the value you set, so each station still needs a clear spec card. Also store the Snap-on TEC12LA Torqometer in its case, and never load it past full scale.

TEC12LA line questions
Is 175 kg·cm close to 17 N·m?
Yes. One kg·cm is about 0.098 N·m, so 175 kg·cm comes to about 17.2 N·m.
Does a Follow-up model exist in this size?
Yes. The TEC12FUA in the same row keeps the peak on a second needle.
Is the TEC12LA right for a 10 in-lb screw?
Not really. That value sits below 20% of full scale, so pick a smaller dial such as the TEC3FUA.
